UNITED STATES PATENT OFFICE SOIL PIPE REDUCER William James Collison, Costa Mesa, Calif.

Application August 28, 1947, Serial No. 771,005

This invention relates to a soil pipe reducer pattern or an eccentric countersunk offset soil pipe reducer.

An object of the invention is the production of a device which is short, stubby and light in weight, and which device requires no coring to mold, all of which produces a device very inexpensive to manufacture.

Another object of the invention is the production of a device having eccentric action or construction, thereby eliminating the use of two additional fittings to install pipe hidden behind the finished plastered wall; very often my device will save cutting timber and walls by turning the device, with the eccentric feature, to fit the occasion.

A still further object of the invention is the construction of a soil pipe reducer device in which there is a primary cylinder having its upper and lower ends in the same vertical plane, and within said primary cylinder is positioned an auxiliary cylinder, which auxiliary cylinder is integral throughout its height at one side with said primary cylinder.

With the foregoing and other objects in view, my invention comprises certain novel constructions, combinations, and arrangements of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

In the drawings:

Fig. 1 is a fragmentary view of a building, shown in section, with part of a sewage hook-up including the device constructed in accordance with this invention.

Fig. 2 is a top plan view of a device constructed in accordance with the present invention, while Fig. 3 is a vertical, central sectional view of the same, taken on line 3--3, Fig, 2, and looking in the direction of the arrow.

Referring to the drawing, in which the preferred embodiment of this invention is illustrated, l designates the primary cylinder, and 2 is the auxiliary cylinder therein. The primary cylinder has its upper and lower ends in the same vertical plane. A partition 3 is formed in the primary cylinder, and this partition 3 is integral with the bottom end of the auxiliary cylinder 2. An eccentric opening 4 is formed in partition 3, at the lower end of the auxiliary casing 2. The formation of the opening 4 produces a ledge 5 at the bottom of the auxiliary cylinder 2. The auxiliary cylinder 2 is integral throughout its height at one side with said primary cylinder I.

4 Claims. (91. 285198) At a point 6 on the outer face of the primary cylinder I, said cylinder is slightly beveled o1 tapered on its outer face towards its upper edge and its bottom edge, Fig. 3. The tapering from point 6 to the bottom edge produces a dual function, in that the lower part of the cylinder fits snugly within the hub I of the soil pipe 8, and in constructing the device it permits the mold and the match plate pattern being pulled out of the molder sand.

In placing the vent pipe 9 in the device, the lower end of said pipe will rest on the ledge 5, Fig. 3.

Upon referring to Fig. 1, it will be seen that the hook-up is entirely between the walls of the building, whereby every part is hidden from view. This desirable feature is obtained by using improved device, as the assembling of the vent pipe 9 with the soil pipe 8 is accomplished without any part of the soil pipe or hub showing in the room. Only the outlet [0 of the water closed bend I I is visible in the room. The bend l I is between the floor and the ceiling of the building. Consequently, no pipe, or pipes, using my new device, are exposed to view outside of the finished wall.

My improved device serves many purposes, especially in some tight places. It eliminates the cutting away of timber, and the use of two additional fittings. The device can be molded from a match plate, five on a small plate, more on a larger plate, and requires no coring to manufacture; this feature alone lowers the production cost about 200 per cent. The device is also light in weight, which is another desirable feature, by reducing the cost of construction. The installation of the device is of a simple nature which is quite a feature during these high-cost times.

While I have described the preferred embodiment of my invention and illustrated the same in the accompanying drawings, certain minor changes or alterations may appear to one skilled in the art to which this invention relates during the extensive manufacture of the same, and I, therefore, reserve the right to make such changes or alterations as shall fairly fall within the scope of the appended claims.

What I claim is:

1. In a single piece soil pipe reducer device, the combination of a primary cylinder having its upper and lower ends in the same vertical plane, an auxiliary cylinder in said primary cylinder and integral throughout its height at one side with said primary cylinder, and said primary and auxiliary cylinders having their upper ends in the same horizontal plane.

2. As a new article of manufacture, a device of the class described comprising a primary cylinder having its upper and lower ends in the same vertical plane, said primary cylinder provided with a horizontal partition intermediate its ends, an auxiliary cylinder in said primary cylinder and having its lower end integral with said partition, said auxiliary cylinder being integral throughout its height at one side with saidpri'mary cylinder, said partition provided with an opening at the bottom of said auxiliary cylinder, and said primary cylinder being slightly tapered or beveled on its outer face in two directions from a' point registering with said partition within the'primary cylinder.

3. A one-piece soil pipe reducer adapted to be placed down in the hub of a soil pipe, comprising a primary cylinder, an auxiliary cylinder within said primary cylinder, and a portion of the side of said primary cylinder forming an integral portion of the entire side of said auxiliary cylinder.

4. A one-piece soil pipe reducer adapted to be placed down in the hub of a soil pipe, comprising a primary cylinder, provided with a partition, an auxiliary cylinder in said primary cylinder above said partition, said primary cylinder being beveled on its outer face in two directions toward its ends, a portion of the side of said primary cylinder above the partition forming an integral portion of the entire side of said auxiliary cylinder, and the upper ends of saidprimary-and auxiliary cylinders being in.the same horizontal plane.
